I thought it was okay, I liked the Felix stuff but everything else was frustrating. I did not like the way S died. She should've been prepared and she should've had a contingency for Ferdinand. It was absolutely out of character for her to die the way she did and for what? Other than "shock" value, her death doesn't really move the plot over nor was it a sacrifice to protect the family. This is a character that was shown to have contingency plans and a network of people to work with her in the previous seasons, yet somehow she puts her guard down, and gave Ferdinand an opportunity to shoot her. She shouldn't have hesitated just like when she put down Duko. The worst part is that she knew he had a chance of escaping, and Rachel also warns her that he's alive. It was a death that could've been prevented easily. Ugh, it was just really messy writing which killed any emotional weight of her death for me. Like before all that, she wrote a letter for Sarah or Felix, as if she knows she's going to die, as if Ferdinand can't be beat. What the heck?
Also didn't like how it was basically all Siobhan who gets the sisters their freedom and pretty much begins the destruction of Neolution. Like it should've been the sisters and Sarah to do that or at least be involved in doing that.
